What's tempeh?

This is an originally Indonesian food product based on fermented soybeans. Molds form (white filaments, Brie-type cheese like) which transform the preparation into a kind of compact cake.

The taste evokes aromas of mushroom, nut and yeast. It is rich in proteins of vegetable origin and poor in lipids.

Usually, the tempeh is cut into slices and fried until the surface becomes crisp.
